How BDLS works exactly?

$

Hello,

 

I've run BDLS report on my system after the system refresh and by coincidence I found following fact:

 

In table EDP13 there are two columns that contain logical names - RCVPRN and RCVPOR. But only RCVPRN column has been modified by BDLS report. The other column is still having old values.

 

<b>Why is this happening? Is this ok?</b>

 

In help.sap.com documentation I've found following information:

 

<i>The report performs the following steps:

1. Determines all the active, transparent database tables whose fields have references to the following domains: LOGSYS, EDI_PARTNUM

2. Converts the field values to the new logical system names

3. Updates the database</i>

 

I am not sure how to understand this.

 

<b>Does this mean that table has to have a foreign key properly defined to be correctly converted? Cannot this lead to inconsistency? If so - is BDLS reliable?

 

Can anyone please explain how exacly BDLS report works?</b>
