Hi Krishna

Take this as an example:

Not sure of the full form. But the structure ITCSY is used in relation with SAPScripts. You can call a Routine in any program in SAPScript.

For eg: if you have a subroutine named ADD_INCOME in a program ZSHAIL_BASIC, you can call the subroutine in SAPScript as follows:

/: PERFORM ADD_INCOME IN PROGRAM ZSHAIL_BASIC

/: USING &var1&

/: CHANGING &var2&

/: ENDPERFORM.

Here the input parameter to the subroutine is var1 and the value returned by the subroutine is var2.

In the program ZSHAIL_BASIC, you have to call the subroutine as

FORM ADD_INCOME TABLES IN_TAB STRUCTURE ITCSY OUT_TAB STRUCTURE ITCSY.

ENDFORM.

IN_TAB is a structure of type ITCSY,which has 2 components, NAME and value.

So in the program, var1(which is sent from SAPScript) , will be stored as IN_TAB-NAME and its value will be in IN_TAB-VALUE. You can utilise the IN_TAB-VALUE and after performing the required operations, the return value should be assigned to table OUT_TAB.

This value can thus be obtained in var2 specified in SAPScript.
