Why are some working and others not? | Solution: One possible reason is that the field, ACTG_QUALITY_CON_REC, in AccountingDef records, is either not populated or it is populated with the wrong condition record.
The field, ACTG_QUALITY_CON_REC, is used to hold a condition record, defined against ConditionRecDef. This condition record is used to tell the Acc... |
Problem Statement: An Accounting rollup may need to be recalculated because at the time of the rollup, enough data may not have existed to calculate the correct value. Once the historical data that the Accounting record uses to calculate the rollup exists in the source record, the occurrence can be recalculated. | Solution: In the InfoPlus.21 Administrator, search for the Accounting record you wish to modify. Find the occurrence number in the history repeat area. Go the the ACTG_MODIFIED_SEQ_# field and enter the history sequence number of the occurrence that you wish to recalculate. Then set the ACTG_RECALC_ROLLUP flag to YES. ... |
Problem Statement: What is the correct tube input for a Twin Box Firebox? | Solution: For a cabin firebox, you should enter the number of tubes against one wall; hence the default Tube Passes defined for a One Cabin Unit is 2.

Problem Statement: The Compliance.21 Compliance Report shows all of the excursions and corrective actions taken for Standard Operating Condition (SOC) items that exceed one or more SOC parameters that are flagged for monitoring. In addition, this report calculates the Compliance percentage and the number of hours that ... | Solution: The problem is caused by "old" open excursions. A CMLimitDef record is configured with limits for each tag where you want to monitor deviations or non-compliance. When one of these limits is violated, an "excursion" is opened in this same CMLimitDef record. When the value for the tag returns to its normal val... |
Problem Statement: The Aspen Compliance.21 User's Manual explains how Compliance reports are configured and activated. Using CMReportDef and ScheduledActDef records, you can, for example, have a 24 Hour Compliance Report such as CMDailyReport.txt, every morning. Windows operating systems do not inherently support file ... | Solution: Using the RGD (Report Generation and Distribution) piece of Human Interface, consisting of TSK_DRPT and TSK_SRPT, it is possible to have multiple file versions of Compliance Monitoring reports. This is done by appending a monotonically increasing numerical extension to the traditional report filename. The num... |
Problem Statement: You just created a new CMLimitDef record and configured some limits. You take the source record's values to a level where a high or low limit should have been violated in the CMLimitDef record and an excursion should have been opened. But, nothing happened! | Solution: Try this "jump start" approach. In either the CMLimitDef record or in the CMGroupDef record, enter a text string in the DISP_DISABLE_REASON field (such as "testing" or "jump start"). Enter NO in the ENABLE_MONITOR field. Then enter YES in the ENABLE_MONITOR field. This should add an occurrence to the repeat a... |
Problem Statement: Aspen Compliance.21 reports show excursions and corrective actions taken for SOC Items exceeding one or more SOC Item parameters flagged for monitoring. If these Compliance.21 Reports are outputting the column headers but not the Compliance information, there are some configuration issues to be check... | Solution: Things to check:
1. Verify that CMLimitDef records that should appear in the report are grouped in a record defined by CMGroupDef.
2. Verify that the CMGroupDef record is named in the domain record in the Compliance.21 domain hierarchy.
3. Verify that the RECORD_NAME field in the CMReportDef re... |

Problem Statement: How do you get the Selection Value for a given SELECT_DESCRIPTION in a Selector record? | Solution: Since the Selection Value is a calculated field, you will need to calculate it as follows:
1st_SELECTION_VALUE + OCCNUM (of the given SELECT_DESCRIPTION) - 1.
Here are two SQLplus query examples:
local x;
x = (select "1st_SELECTION_VALUE" from calc_error_type) +
(select occnum from calc_error_type.1 where ... |
Problem Statement: Daylight saving time presents a problem to Aspen SQLplus when retrieving data from the AGGREGATES table. The day has only 23 hours when moving from standard time to daylight saving time. Likewise, the day has 25 hours when moving from daylight saving time to standard time.
Aspen SQLplus skips the h... | Solution: The parameter DSADJUST controls AGGREGATES calculations around daylight saving time transitions when the period is greater than or equal to two hours. When 0, DSADJUST causes Aspen SQLplus to not adjust the first interval of the transition day and to adjust time stamps instead. When 1, DSADJUST causes SQLpl... |

Problem Statement: How does Aspen InfoPlus.21 determine which file set to shift into? | Solution: First Aspen InfoPlus.21 checks if there are file sets with a status None. These are empty file sets. If there are empty file sets, the repository will shift to the empty file set (of status None) with the lowest number.
Secondly, if there are no empty file sets, the repository will shift into the oldest file ... |
Problem Statement: How can I select the most recent trend value and time of a tag prior to a given time? | Solution: Use a subquery with the MAX function to find the most recent trend time prior to the given time. Then select the trend time and value based on the results of the subquery.
The following example illustrates this technique:
select ip_trend_time, ip_trend_value from ATCL101
where ip_trend_time =
(select max(ip_t... |
Problem Statement: How can I split a long EXECUTE or EXEC command over several lines? | Solution: Place each part of the EXECUTE or EXEC command on a separate line enclosed in single quotes. Do not place a comma between each segment.
For example, the query
EXECUTE 'CREATE INDEX a ON b(x, y) '
'TYPE IS HASHED' ON p;
splits the command
EXECUTE 'CREATE INDEX a ON b(x, y) TYPE IS HASHED' ON p;
onto ... |
Problem Statement: The Aspen InfoPlus.21 standard tag set has a field called IP_ARCHIVING. The options for this field are "ON", "OFF", and "PAUSE". What is the difference between "PAUSE" and "OFF"? | Solution: "PAUSE" suspends history storage for a tag but still allows the viewing of history already collected. To resume history storage, set the field IP_ARCHIVING to "ON".
Setting IP_ARCHIVING to "OFF" suspends history storage and also makes history already collected for the point unavailable. To resume history sto... |
Problem Statement: How to synchronize the scrolling in all the report that are currently displayed. | Solution: Sometimes when we want to compare the information in two or more reports, especially for some information only exist in the FullSolution report which case comparison is not enough for us.
