Update multiple records in one infotype

[dan_spitzig]

How can I update all records for a given PERNR in a specific infotype?  I am trying to use FM HR_MAINTAIN_MASTERDATA, but it seems that the PAKEY must be specified for each call to the FM.  Basically, what I am trying to do is set the TELNR (among other fields) for all records for a given PERNR in PA0006 to the same random value.

This can be done in multiple ways -

One of the ways is to query the IT0006 and get the Start Date and End Date for the Records.

Then prepare a LSMW - with which you provide the necessary key data fields to identify that record and provide the TELNR value. Let me know if you have any more questions on this approach.

I am new to working with infotypes. Will I have to get the start and end dates for each record in each infotype? This could involve 100K+ records in each of the 7 infotypes we are updating?What is a LSMW, and how do I prepare it?

I am using the function module HR_MAINTAIN_MASTERDATA to update IT 0009 (PA0009), making a separate call for each record. If there are records for a single PERNR, but with different subtypes, it is changing all subtypes to '0'. I have the PSPAR filled with all the PAKEY values to identify the record to be updated. I also have those fields, as well as the fields to be updated, loaded into the PROP_T table. How can it change my infotypes to '0'?
