Paul, there is no approval for entries coming from Third party as you said it has do be handled via third party or a custom application which Rose can explore before bringing into SAP, Cats_da is for display.
Also Rose is talking about Time events from third party which updates Teven,, ie IT2011, I don't think she intends to use CATSDB or CATS for it. As its not being implemented
Rose, There is no approval in standard system for posting events in SAP from third party and
also no approval for entries in time evaluation!! You only get message pool for Time admins which can be corrected via Pt40.
I am not sure when the approval should take place? Is it before loading the data into IT2011?
How the approval process to be configured in the ESS MSS and at the ECC/R3?
Actually I need some inputs on how the time approval process should take place?
>>>>>>>>> You need to use clock in clock out corrections for approval process
