Here you can find all LMP codes and its descriptions: https://support.ca.com/us/product-content/recommended-reading/technical-document-index/ca-licensing---lmp-listing.html
For CA SymDump/Batch you will find at first:
... CA SYMDUMP BATCH PO SYMDBA00200 SYMBAT002 MMXAPL002
SYMDUMP BATCH MIPS PO SYMBTM00200 SYMBTM002
SYMDUMP BATCH MSU PO SYMBTU00200 SYMBTU002
There is no difference in the function or way to install these three products. The difference is in how the contract is layed out.
All three products need the PO LMP key.
You will also find
... CA SYMDUMP BATCH RX SYMDBA00200 SYMBAT002 MMXAPL002
This is because CA SymDump Batch shares a component with CA Optimizer/II.
The LMP Product Key Certificate for CA Optimizer/II Runtime - 'RX' - is required and should also be included.
That means you need both LMP codes, PO and RX, for CA SymDump/Batch.
