I have a program that has several statements starting with this CALL_METHOD_* and then some parameters. Is this the same as PERFORM Z_TEST_1(Para1, para2,etc..).
For example, CALL_METHOD_CHECK_ALL 'DOC_TYPE' DOC_TYPE ZTABLE1-fielda_A.
Where can find source code for these CALL_METHOD statements?
What are the CALL_METHOD statements?
