I have created one script for MM01 transaction and have done coding also in the ABAP ....ENDABAP Block but I am not able to see the values of local variables and internal table used inside this block during debugging of ECATT script.
Though I can see values of the globally defined variables in the Parameter list.
Also, in the command interface what is the relevance of
C Fld Check
G Fld Get
S Fld Set
I Fld Input
O Fld Output
Though I have used S Fld Set for mapping my parameter fields with screen fields. Rest I am not aware of the purpose and use.
