AW: Adding all the box quantities for a item

["myibmi" <myibmi@xxxxxxxxxxx>]

RPGLE Education?

How many box fields are in the item master file? (i
Less than 10, why do you think you need a subfile?
I would'nt do that, unless I have a lot of time, or it is a beginner task.

Hi,

They are like below :-


On display file screen (a subfile)


Enter item number :-   .................


Once we enter item number then program need to look for this item number in
a item master file and if it successfully finds an item in it then it
further checks corresponding boxes ( for each item there might be multiple
such boxes  in box id field of this same item master file)  and for each
such box there is corresponding 'quantity' field is there in same item
master file so we need to add all such quantities for all the individual
boxes and then finally sum it up and show on display file screen.

Just for more clarification:-

Box no.       Quantity
Box 1           5
Box 2            7
Box 3           15

Then just for example if all the above 3 boxes are there for item number
'xyz' then
Program should be able to read this item master file for a specfic item
number which is entered on display file(which is a subfile with record,
control, header and footer but does not contain column headings on display
screen for these boxes but such multiple boxes are present in this item
master file for each such item number )

And then program should add quantities for all these boxes and on the
display file(subfile) it should be able to display like :- "Tot
Quantities:     27   Sum"





Thanks a lot.. ..
