1943752 - SYNTAX_ERROR Dump in Customer Program or Customer Exit Code after Upgrade to BW7.4

• You get SYNTAX_ERROR dump in a customer program or customer exit code (eg. Include ZXRSRU01).
• The exit code could be the logic for customer exit variable in a BW query, or exit logic in a transform rule, update rule, transformation, DTP or infopackage.
• When you carry out syntax check for the code, you find syntax errors. It could be like the below for example:

Include ZXRSRU01  (can also be other custom code)

"RRRANGEEXIT" must be a flat structure. You cannot use internal tables,

strings, references, or structures as components. -

or:

you cannot use offset and length specifications

    with fields of type "STRING" or "XSTRING"

 Call stack could be:

IF_RSROA_SMOD_COMP_MEDIATOR~OLAP_BADI_DEFINE CL_RSROA_SMOD_COMP_MEDIATOR===CP
IF_RSROA_SMOD_COMP_MEDIATOR~OLAP_BADI_DEFINE CL_RSROA_SMOD_COMP_MEDIATOR===CP
IF_EX_RSR_OLAP_BADI~DEFINE CL_IM_RSR_OLAP_BADI===========CP 
IF_EX_RSR_OLAP_BADI~DEFINE CL_EX_RSR_OLAP_BADI===========CP 
IF_EX_RSROA_OLAP_BADI~DEFINE CL_EX_RSROA_OLAP_BADI=========CP 
DEFINE CL_RSR_USER_EXIT==============CP 
READ_USER_EXIT CL_RSR_RRI2_DESCR_GENERATOR===CP 
GENERATE_DESCRIPTION CL_RSR_RRI2_DESCR_GENERATOR===CP 
GET_NEW CL_RSR_RRI2_DESCRIPTION=======CP 
GENERATE CL_RSR_RRI2_QUERY_GENERATOR===CP

Syntax error happens when:

CALL FUNCTION 'EXIT_SAPMRSRU_001'

• The customer exit code has been working well before and this syntax error occurs after upgrade to BW7.4.
