ABAP code example for Function Module ISU_M_FILE_HEADER

The ABAP code below is a full code listing to execute function module ISU_M_FILE_HEADER including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

DATA:
ld_y_info  
 
 TYPE TEMINFO
.



DATA(ld_x_path) = some text here


DATA(ld_x_file) = some text here


DATA(ld_x_cpgfs) = Check type of data required

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_y_info
 
 TYPE TEMINFO ,
ld_x_path
 
 TYPE TEMFD-PATH ,
ld_x_file
 
 TYPE TEMFD-FILE ,
ld_x_cpgfs
 
 TYPE TEMFD-CPGFS .



ld_x_path = some text here

ld_x_file = some text here

ld_x_cpgfs = Check type of data required
