LANSA Composer 3 introduced the ability for a processing sequence to call a processing sequence. This feature enables reusable processing sequences to be developed, which can be called from a number of other processing sequences. To support this feature, a processing sequence may now have outbound parameters defined.
Objectives
- To split processing sequence iiiTUTSEQ07 developed in exercise LIC009 into two parts
- iiiTUTSEQ07 will now call processing sequence iiiTUTSEQ7A which will contain the steps to:
- Use CONCAT to produce the output file path and name
- Run transformation map iiiTUTMAP03 to extract Employees to XML file based on an input CSV file of employee numbers
- Use FTP to send the output employee XML file to the output folder.
Note
This is a simple example of calling a processing sequence from another processing sequence. It does not represent an ideal solution. For example, since multiple employee XML files may be output by each run of iiiTUTSEQ07, it would be more efficient to include only steps 1 and 2 in the processing sequence iiiTUTSEQ7A. After calling iiiTUTSEQ7A, iiiTUTSEQ07 could use a DIRECTORY_LIST and FTP all output files to the output folder.
