Line Item Tab wise Auto Sequence in Detail Form - Unifier

Hi All,

My requirement is to generate Line Item Tab wise Auto Sequence numbering  in Detail Form of Unifier BP.

For e.g. We have a BP with two Tabs named Tab1 & Tab2. I want to generate the autosequence number as shown below:

Tab1 has 3 line items as below :

No	Auto Seq. No.	Item
1	TAB1-0001	Tab 1 - Item 1
2	TAB1-0002	Tab 2 - Item 2
3	TAB1-0003	Tab 3 - Item 3

Tab2 has 2 line items as below :

No	Auto Seq. No.	Item
1	TAB2-0001	Tab 2 - Item 1
2	TAB2-0002	Tab 2 - Item 2

I know we can generate auto sequence numbering in detail form by using data element of data definition 'System Auto Sequence' type.
