Hi,

W_ITEM TYPE EBELP.

This will create a workarea of type EBELP.

ZPURI-EBELN = ZPURH-EBELN.

Regarding this one, u can see TABLES statement in the begining of the program.

When u declare something with TABLES statement this will create a workarea of that table type.

So ZPURI and ZPURH are tables this will create a workareas of type, ZPURI and ZPURH. And EBELN is common in both tables that is why they are assigning the value of ZPURH-EBELN to ZPURI-EBELN.

Thanks & Regards

Hi rams,

Before ZPURI-EBELN = ZPURH-EBELN.

there should be a select statement to get the records from ZPURH table.

W_ITEM TYPE EBELP. EBELP is the Purchase Document Number . So w_item is a variable of type EBELP.

ZPURI-EBELN = ZPURH-EBELN. Moving the value of ZPURH-EBELN to the variable ZPURI-EBELN. seeing the code ZPURH ZPURI are z tables and the fields EBELN of both the tables seems to be the screen fields, but not any internal tables nor work areas.

ZPURI-EBELN & ZPURH-EBELN are the screen fields.
