Summary :
When executing a report group in SAP, if more than 999 INDX blocks are requested, the system may terminate with error GR 215, indicating an internal error. To prevent this, users can increase the memory limit by altering the INDX_BLOCK_SIZE parameter in the FGRWFDS0 include (from release 4.0: GREP_BLOCK_HASH). Standard settings allocate 100,000 x 999 bytes; however, expanding INDX_BLOCK_SIZE to 500,000 may circumvent the error. Changes should be followed by the regeneration of affected report groups via transaction GR55. It's essential not to exceed an INDX_BLOCK_SIZE of 999,999.
