APO - Detailed Scheduling Planning Board - ABAP Error when accessing it

[former_member384222]

Hi,

in APO (7.3.) a colleague call the scheduling planning board /SAPAPO/SDPC0, enters the overall profiles and the resources in the work area. all fine. when trying to access the board with F8 an ABAP error appears immediately. When I do it with the same data I face no problems...what might be the reason? the ABAP error does not show any nr nor any additional info. It says only: the SAP application had to be terminated due to an ABAP error. It shows just the date, time and IT transaction. nothing more.

St22 shows:

What happened?
Error in the ABAP Application Program

The current ABAP program "/SAPAPO/SAPLCDPS_PRESENTATION" had to be terminated
because it has
come across a statement that unfortunately cannot be executed.

Error analysis
An attempt was made to access a field symbol that has not been assigned
yet (data segment number "-1").

That error occurs if
- a typed field symbol is addressed before it has been set with ASSIGN,
or
- a field symbol is addressed that points to a row in an internal table
that has been deleted, or
- a field symbol is addressed that was previously reset using UNASSIGN,
or that pointed to a local field that no longer exists, or
- a parameter of a global function interface is address, although the
corresponding function module is not active (is not in the list of
active calls). The list of active calls can be taken from this short
dump.

any Ideas? thanks for any hints!
