    Hope this helps

    Hi,

    While executing project info system (CN41N), all the datas are called from varios tables such as PS / FI / MM module etc. If there are more objects such as WBSE / network activity / material components in the info-system then this will take more time for executing. You can follow any of the the below methods.

    1. Increasing the memory allocated to PS component. This details can be checked with your BASIS person.

    2. While slecting the DB profile un check the details which may n't relevant fro your reports such as logistic / accounting / project structure. You can execute one report at one time.

    3. Back ground processing of the report.

    Please find reply for the same issue also.

    The memory which can be managed by the logical database is approx.

    100 MB. You can use the following rule of thumb to calculate the

    allocated memory of your selection:

    [( sum of projectdefinitions + sum of WBS elements + sum of networks and orders ) * 1 KB + ( sum of activities ) * 4 KB ] *2,5 = memory consumption

    Further objects - as relationships, capacities, ... will increase

    the memory consumption. (see note 107605)

    You can find out the number of objects bein used using the "Test selection scope" (CTRL+F12) button in CN41

    Other recommendations are:

    1) Check the profile (parameter "rdisp/PG_MAXFS") with your Basis

    colleague and adjust upwards (Note 133909)

    2) Select a smaller range of objects by using status schema

    or more dynamic selections. Please review SAP Note 206264.

    3) Please review also 107605, which gives you further information

    concerning the selection in Project Information System.

    Hope this will solve your problem.
