Adding columns to existing view

Hi list,

This question seems basic, but will be very helpful.. What's the impact of
adding another column to a business view ?? Suppose if I go to a business
view design mode, add 1 or 2 columns from the table, and generate it, will
it cause any problems where this view is aleady used ?? I know if any colums
are removed it can cause problems, but adding a column shouldn't affect any
of the places where the view is used, Am I right ?? Or Do I have to open the
places (UBE/APPLN) and save them again.

Thanks in advance.

Prads.

Prads,

1 - You're 100% right! It's fine to add column(s) to view(s); if you are not using them (as adding'em to your app's or ube's), they're just going to be ignored. There's no need to look for/revalidate objects/statements ... :)

2 - You're right again, problems start ONLY when the apps/ubes do NOT find the deleted ones!

As far as I can tell, there are no basic/deep/hard/difficult questions, at least here, on the JDElist; they are just questions in need to find their answers. And, usually, they do, here on the JD... :)

Prads, Adrian

I just want to confirm Adrian's answer and make a little, maybe obvious addition.

* append you new fields to the end of the original BSVW
* never change the order of the originally existing fields of the BSVW

At last I would tell that we extended original BSVWs more times and we haven't experienced any problem.

Hi Prads,

We already modified a business view in a existing report and the report did not work anymore. If you don't want the same error make sure all the column added are at the end of the business view and you should not have any error.

One of the reason for that is the business view "translator" from OneWorld was doing something like that : select field1, field2 from table order by 1,17,22... So you can imagine what was appening when inserting a field between column 17 and 22, Your View was still sorted on column 1,17,22... Wich is now 1,17,23...

We did a call to JDE tech support and they were supposed to fix the translator to be : select field1, field2 from table order by fieldname, fieldname, fieldname instead of 1,17,22

Just a correction to my previous reply.

We extended only simple, single table based BSVWs and haven't experienced any problem.
We haven't currently any experiences about extending complex, joined BSVWs.

Dear Zoltan,

Business View Design appends new fields to the end of the original BSVW by the default and we never change the order of the fields of the BSVW. Nevertheless when I append new field to existing BSVW and generate it again it does not work. Report that uses this BSVW prints out empty fields.

Any ideas?

I wonder if this is a case of needing to go into the 'C' code and making
sure you populate the new fields? I know sometimes even some master business
functions (Edit Line in R03B11Z1I, for instance)using a table/view don't
populate all the fields and the 'C' code had to be modified. And these were
"as is" from JDE.
