Points to Note when Converting
Relationships 
Conversion of the relationship categories married couple, wife and husband (0020, 0021, 0022)
The relationship category 0020 no longer exists, and can be replaced by a customer-specific relationship category, if required.
BUR004 Marriage replaces the relationship category 0021 Wife -> Husband.
BUR004 Marriage replaces the relationship category 0022 Husband -> Wife.
This means that when both relationship category 0021 and 0022 are converted to relationship category BUR004, you have to swap one of the partners in one or the other relationship category round, because you have to define either the husband or the wife as partner 1 in BUR004.

You swap the business partners for one relationship category by setting the sequence indicator for either of the two relationship categories in the IMG activity Relationship Category, prior to executing the conversion report RFTBUP02. You will find further information under Check Customizing Structure.
Conversion of the relationship branch/head office (0030)
The relationship category 0030 no longer exists, and can be replaced by a customer-specific relationship category, if required.

You have to make sure that this new relationship category is assigned differentiation category 1, in other words, it is company code-dependent, otherwise an error message appears when the conversion Customizing is checked.
Conversion of the relationships group subsidiary/parent, joint venture/company, OHG, KG with general partner, GbR with partners, affiliated to (0050, 0100, 1000, 1001, 1002):
Using the conversion report for business partner relationships, the relationships 0050, 0100, 1000, 1001, and 1002 are transferred to relationship BURC01 shareholder. In the standard system, in a business partner relationship with the category shareholder, business partner 1 is the “lower”, (in other words, the subordinate) and business partner 2 the “superior”, (in other words, the superordinate) organization. You can assign as many of business partner 1 to business partner 2 as you wish.
Partner 2 is the shareholder; partner 1 is the one from whom partner 2 receives the shares (issuer).
If partner 1 and partner 2 exist in more than one of these relationships (for example, as a group or an affiliate), only one of the relationships is converted. All the others receive an error message.

If you want to, you can keep both relationships with both partners. After you have created your own relationship category, you can then convert the corresponding relationships again.
When converting the partners, you must ensure that for relationship categories 0050, 1000, 1001 and 1002 the following applies:
Partner1 àPartner1 Partner2 à Partner2
whereas for relationship category 0100 the following applies:
Partner1 àPartner2 Partner2 à Partner1
You can see this in the conversion Customizing for the relationship categories. If you set the sequence indicator for relationship 0100 here, partner 1 and partner 2 are swapped round.
The reason for this swap is that in relationship 0100 partner 1 is the organization, and in relationship BURC01 partner 2 has to be the organization.
In addition, the following relationship categories were created, which you can use instead of relationship category BURC01 Shareholder:
· FSB001 partner of
· FSB002 subsidiary of

Some SAP Business Partner relationship categories require one of the business partners to have a specific role category too. When you convert the relationship category BURC01 Contact Person, this is subsequently assigned the SAP Business Partner role Contact Person.
