:S Table Buffering Problems

Question

Hi I am brand new to SAP/ABAP and I am struggling to get rid of a warning I get for a piece of code. Any help would be much appreciated.
Cost Center Cutback object has warnings performance check: (1). <b>Generically Buffered Key Area  for Table CSKS not Completely.</b>
Here is the code the warning is pointing to
  SELECT kokrs kostl INTO TABLE gs_cskskey FROM  csks
         WHERE  bukrs EQ gs_key_costcut-bukrs
         AND    kokrs IN gr_kokrs
         AND    kostl IN gr_kostl
         AND    bukrs IN gr_bukrs.
Is the problem here that the table buffer is not getting properly filled for some reason???

Answer 1

James,
Your table is Generic buffering table. If you read a record from a generically buffered table, all records whose the left-justified part of the key corresponds to that of this record (generic key fields) are loaded into the buffer.
This left-justified part of the key is determined in this field by entering a number n of key fields. The first n key fields of the table are thus the generic key fields.
The number entered must be between 1 and key field number -1. For example, for a table with 6 key fields, only values between 1 and 5 are allowed.
The value to be entered should be selected so that the generic areas, that is, the set of records corresponding to a record in the generic key fields are not too small.
This you can see at SE11==> Table name ==> Technical settings. There you can find one field called no of key fields there.
One ways is
Go to Change mode and change this you can avoid this warning.
Second way is
Try to pick all the key fields in seelction. ie KOKRS,KOSTL, DATBI. I believe this way you can avoid this warning.
