You can access all the fields of the table zrmmast using the structure it_mast

ie you can say it_mast-status or any field followed by it_mast-...

Hi,

define work area

wa_mast type t_mast.

you need to loop at it_mast into wa_mast and then refer

select ...... where status = wa_mast-status..

HI,

Your IT_MAST is not a strucutre dude..

its an internal table thats why you cannot refer its fields like that,

what you can do is in you second DATA statement use as follows

DATA: IT_MAST like line of t_mast.

Hi,

If you want to create a work area create it as I have told

<b>DATA: wa_area like line of t_mast.

OR event better

DATA: wa_area type zrmmast.</b>

t_mast is an internal table and for creating a work area you have to use its line type.

Hi willard,

it is difficult to know your situation in detail.

post your relevant code (don't forget to use Code button above) and people will flood you with answers.

In the meantime, find out the difference between structures, internal tables, types ans so on.
