Object Method Usage

[Dart, Jocelyn]

Hi Diane/Kjetil,
No it's not as simple as changing the flag from dialog to background - if
it was marked as dialog in the first place it was usually because the way
that method is coded it does require user involvement, e.g. it calls a transaction
with screens that need to be filled in by someone. You need a method that
has code that does NOT require user involvement.  Which it sounds like you
already have.
 
I'm guessing that the CreateFromData method (you don't say which object?)
is a true background method that therefore doesn't use screens at all and
is probably, even better, a BAPI?
So screen sequence should not be an issue.  The only question is does it
let you add the data you need to. If it does then you can use it.
 
As a general rule if you want to create a background method you need to
find a background way of performing the activity such as:
1. BAPI - generally the best choice of all as it is performance efficient
2. Some other function module(s)
3. Some sort of batch input technique such as CATT, BDC or CALL TRANSACTION USING.
Then code the method to use this.

Well, there is always the "easy" way of making a subtype and changing the
method from dialog to background. If you have some nice function modules to
call which do their tricks nicely you shouldn't have a problem. However,
all kinds of problems _may_ occur.
 
I tried to make a background method to release a LIV invoice with payment
blocking (no, I still haven't completely solved the good old case I asked
about here a while ago) due to amount limits on invoices without reference
to purchase orders. This is necessary as none of the BUS2081 methods will
release these invoices. The method used batch input to start MRBR, enter
the required data and release the blocked invoice. No-go since SAP uses
Fancy Tables (FT (tm)) in the implementation of MRBR. The reason is that
for these tables you can not address rows etc in the way you could with
"old-style" tables.
 
After a while (depressing, but true, it took quite a while) I realized that
I could use the "Select all" button since I would only have one row (as I
specified the invoice number). That should do the trick, right? Not at all,
SAP developers have ensured that life will be a pain no matter what you
try. So in the end I had to make it a dialog method, and thus someone has
to execute that step. All they do is execute, and it is gone without the
executing agent seing anything happening.
 
You have been warned :-)

Good afternoon all.  We want to use an object type method to create a SAP
record.  We want to call the method in the background and create the record
without user intervention.  The current method we want to use is a dialog
method.  Does anyone know of a way to change a method from a dialog to
allow
use of method in background or is this an impossibility.  There is a
CreatefromData method, but apparently it does not provide the same screen
sequence.  Has anyone else ran into this problem and if so what was the
solution???  Thanks in advance for any help or suggestions in this matter.
