Usually, long-term supplier's declarations are issued to external customers. In intercompany sales within the EU, however, the receiving subsidiaries might require supplier's declarations, too.
Based on billing documents for intercompany sales, the administrative unit representing the supplying company code can issue long-term supplier's declarations to the administrative unit representing the receiving company code.

The feeder system can transfer extracts from billing documents for intercompany sales to the SAP GTS system. These extracts are stored there as system proposals for the issue of long-term supplier's declarations. Processing these proposals, the program /SAPSLL/CREATE_ICEXCH_LTSD_OUT creates supplier's declarations. The program is intended for background execution, but can also be started using transaction Exchange of LTSDs Between Administrative Units (transaction code /SAPSLL/LTSDOUT_IC).
