Guidance on Internal Tables in BSP's & ABAP Functions

Morning all,

disclaimer: I searched the forum and the blogs but couldn't see anything on this and I think it is a subject which could help others

I'm back on my proof of concept app and I have a question on the fundamental rules and reasons for when to use WorkAreas, Structures, TableTypes, InternalTables in BSP's.

From my BSP, in the OnInputProcessing Event I am trying to

call an ABAP function to send an email.

I have tested the concept of sending an email with a Report in SE38 and

it works, and now I am trying to put this functionality into my BSP.

The problem is, in the Report in SE38 an Internal Table is created

and used to pass contents to the Function, but in a BSP it seems

we cannot use Internal Tables, what do we do ?

In the report in SE38 I have this line:

reclist like somlreci1 occurs 1 with header line

In the BSP I made an Internal Table in the Parameters area with:

it_reclist TYPE somlreci1

Then in the Event, I have ABAP similar to my report and I try to append data

to the Internal Table and then I try to assign the Internal Table to a table of the

SendEmail function as follows:

it_reclist-receiver = 'user@company.com'. "<-- change address for testing

it_reclist-rec_type = 'U'.

append it_reclist.

• Send Message

CALL FUNCTION 'SO_NEW_DOCUMENT_SEND_API1'

EXPORTING

document_data = docdata

DOCUMENT_TYPE = 'RAW'

PUT_IN_OUTBOX = 'X'

COMMIT_WORK = 'X' "used from rel.6.10

• IMPORTING

• SENT_TO_ALL =

• NEW_OBJECT_ID =

TABLES

• OBJECT_CONTENT = OBJCONT

receivers = it_reclist

When I check this I get the error message:

"IT_RECLIST" is not an internal table - the "OCCURS n" specification is

missing.

My problem, I have not seen documentation anywhere or a blog giving guidance on

how, when and where to use Internal Tables in BSP's.

Todate when I have come across this problem I have by trial and error gone through trying

creating TableTypes, Structures, WorkAreas and passing the data between them all to finally try to get the data into a Function call.

But I have always just used trial and error without any rules or understanding of when to use what/which and why ?

Can anyone advise, using the above case as an example, how to take some code which has been proven in an Abap Report and migrate that code to a BSP, and how to deal with the Internal Tables and what the rules are for dealing with the Internal Tables and when to use WorkAreas, Structures, TableTypes, InternalTables and why ?

If this question is unclear I will add more to try to make it more clear.

Thanks for your time all,

Milan.

p.s. I didn't finish getting my BSP Extension to work, but I'll move back to that once this proof of concept app is finished.
