Example for V1, V2 updates

[Former Member]

Hi Experts,

1) I know the diference btwn V1(Updates immediately, locking involved, not sharing etc) and V2 updates. But, let me know the real world examples for both.

2) And in some cases, I hv seen COMMIT work after the statement of MODIFY Z_DB_TABLE statement, but, when I updated my Z table, i did not used this commit, but, still its working, so, why in some cases they used COMMIT after MODIFY a Z table?

Hi,

The real time example can be in this way for booking a movie ticket needs to be updated immediately...

this should be done using V1 updates because we have to block the seats so that no other system can block it.

but something like master data that which movie is going to release next in the theatre can be done in V2 update because that does not require any immediate effect or any current involvement of other system to it as it has to be done by admins.

Check the following link to better understand V1 and V2 updates....

Check the FM MCV_STATISTICS_DELIVERY.

This FM is used to update the Delivery information in the LIS.

If you look at the bottom part of the code, it is Calling different FMs based on the Updates e.g. V1, V2, V3 etc.

It uses the table FM MCV_STATISTICS_LOWEST_LEVEL to determin which Update it needs to use. Inside this FM, it is using so many factors to decide which update to use. One of the factor is the field KBTCH in the table TMC2S.

1) have you looked through the help files?

2) There is an implicit COMMIT when a report ends normally.

I hv seen the provided link in the 1st response and i found the below, statement, but, did not understand!!

"Let us assume that a transaction makes planning changes to a material and balance sheet, and updates two sets of statistics.

Each of these changes is represented by means of an update module (call update function module) in the update request - the two planning changes by a V1 update module (time critical), and the statistical changes by a V2 update module (less critical). (The V1 modules have priority, although the V2 modules are usually also processed straight away)."

Only am looking for that, Wht is a example for V2 update in SAP?
