Change of LDB from PNP to PNPCE

Question

HI All,
   I have a HR program where LDB PNP is used. Now I need to change the LDB from PNP to PNPCE. Can any one please tell me what are the mandatory change I need to do in the program after changing the LDB.
Thanks & Regards,

Hi,
Purpose
The PNPCE logical database supports the evaluation of HR master data. It includes the functions of the PNP logical database and offers additional evaluation options. Therefore, you should use the PNPCE logical database instead of the PNP logical database for all new developments.
The enhanced functionality of PNPCE in comparison to PNP essentially concerns the evaluation of Concurrent Employment, that is the possibility to group evaluate several assignments/personnel numbers of a person. The new events 'GET PERSON' and 'GET GROUP' as well as an enhanced syntax for the INFOTYPES statement (addition AS PERSON TABLE) for the procurement of infotype data enable you to use the new functionality. The use of these new functions is optional. You can run a PNPCE report that does not use the new events and the addition for the INFOTYPES statement in a PNP-compatible session. Since the PNPCE also has an improved selection screen, each report benefits from this even if the report does not use the functions for evaluating Concurrent Employment.
Prerequisites
A report that wants to use the PNPCE must enter this in its report attributes under Logical database.
In addition, the PERNR structure must be declared in the report using the 'TABLES PERNR' statement. You can only use the PERNR structure again in certain circumstances. The use of the 'GET PERNR' event is therefore forbidden. Instead, use the 'GET PERAS' event. Except for the PERNR-PERNR component, all other components of the PERNR structure are no longer filled and have initial values. This kind of programming (with the exception of PERNR-PERNR) therefore not permitted.
In addition to the 'GET PERAS' event, you can also use the GET PERSON' and 'GET GROUP' events. To be able to use these events, you must declare them using the NODES statement (NODES PERSON', 'NODES GROUP', or. NODES PERAS').
Explanation of Terms
If the 'GET PERSON' and 'GET GROUP events and the 'AS PERSON TABLE' addition for the INFOTYPES statement are not used, the report indicates that it does not require the functionality for evaluating Concurrent Employment. In this case, the report runs in a PNP-compatible session. This is referred to as PNP mode in the following documentation. On the other hand, if the report uses the functionality for evaluating Concurrent Employment we refer to CE mode.
Features
Process of an Evaluation
The PNPCE selection screen offers you as standard a range of functions that you can use to restrict the personnel number and person selection. These are discussed in more detail in the following sections. The process is initially as follows regardless of whether the report runs in CE or PNP mode. All available functions and selection conditions leads to the selection of personnel numbers. If you use the sorting function, this set of personnel numbers is then sorted according to the sort criteria you selected. In PNP mode, the GET PERAS event is triggered as a result for each personnel number.
In CE mode, the persons belonging to the personnel numbers are determined first for all personnel numbers selected. The GET PERSON event is then triggered for each person. The person ID is specified in the OBJID component of the PERSON structure. PERNR_NUM contains the total number of personnel assignments (= personnel numbers) that this person has and the ALL_PERNRS table, which contains a list of these personnel numbers regardless of whether they were actually selected or not. The SELECTED flag is set to X for the personnel numbers selected. The flag is initial for all personnel numbers that are not selected. The PROCESS flag specifies whether the personnel number should be processed in the rest of the process. This flag is set to X by default for the personnel numbers selected. However, the report can set or delete this flag at the GET PERSON event for all personnel numbers. In this way, report and logical database communicate with each other which enables the report to control the rest of the process.
In the next step, the logical database groups all personnel numbers of a person that are to be processed (that is, all personnel numbers that have the PROCESS flag set). The report can control the type of grouping using the PNPCE_GROUPING_FROM_PAYROLL flag (normal or payroll grouping) and using the PNPGPRSN (grouping reason) and PNPGPVAL (grouping value) parameters of the selection screen. The GET GROUP event is triggered for each group of personnel numbers determined. The GROUPING_REASON and GROUPING_VALUE components contain the grouping reason and grouping value of this group. The number of personnel numbers that belong to this group and that are processed subsequently is in PERNR_NUM. The included ALL_PERNR table contains a list of these personnel numbers with additional information. The SELECTED flag specifies whether the current personnel number was originally selected (flag is set) or was marked by the report as to be processed. GROUPING_BEGDA and GROUPING_ENDDA contain the validity period that the personnel number has for this grouping. The NO_AUTHORITY flag is set if there is insufficient authorization for a personnel number. This personnel number is not processed further. The SORT component defines a standard sort order for the personnel numbers of a group. The report can change this by overwriting the values. In this way, report and logical database communicate with each other, which controls the further processing sequence of the personnel numbers.
The GET PERAS event is then triggered for all personnel numbers of the group (with the exception of the personnel numbers for which no authorization exists) in the sequence defined by the SORT component (see above). The SELECTED, GROUPING_BEGDA, and GROUPING_ENDDA components have the same meaning here as with the GET GROUP event. The PROCESSED_BEFORE flag specifies whether the personnel number has already been processed once before (it is possible that the personnel number belongs to several groupings and has been therefore been processed several times).
