The following syntax error occurred in the program SAPLCN2002_ACT :
""LS_BAPI_TE_ACT" and "EXTENSIONIN+30(960)" are not mutually convertibl"
I researched this error and found this note. OSS Note 637345 specifies to create dictionary structure with the same fields as my CI_AFVU but make all the fields CHAR fields. Then, change structure BAPI_TE_NETWORK_AVTIVITY to use this new append structure.
The problem is the structure BAPI_TE_NETWORK_AVTIVITY comes with pre-assigned append structure CI_AFVU. To change this would cause a MOD to the SAP code. In my organization, we are not allowed to make modifications to the SAP code.
