Message Mapping- 3 problems

Question

Hi,
1)I need some information regarding Message Mapping. I need to map the field TDLINE of segment E1EDKT2 of IDOC ORDERS05 to the target fields. But based upon the index number of the record of this segment, I must map it to different fields (eg.E1EDKT2[10], E1EDKT2[3]). How can I incorporate this in Message Mapping?
2)And one more scenario is as follows.Use PARTN if exists or use LIFNR to map to target and it must satisfythe conidtion PARVW = AG. Should we need Java code or can we achieve this using two 'If' conditions.
3)We are looping at a source segment and it has multiple  occurances.How to create multiple segments in target based on condition.
Can anyone help me.
Thanks,
Srinivas

You can use the index function (with SP13):
E1EDKT2* - index
                  equalS
    constant(10) /     
                         ifWithoutElse - target
TDLINE - removeContexts /
check the correct context

Sure you can chain if statements:
        PARVW
              equalS 
constant(AG) /     
                     ifWithoutElse
              PARTN /            
                   PARTN - exist - if - target
                              LIFNR
This mapping assumes, that PARVW = AG is available, when PARTN is available.

Here is a pattern:
condition - createIf - target
condition has to be a queue of true and false with the same occurrency as source.
All sub nodes of source are now arranged correctly under the target node.
