in our application software is 9,0. Is there a way to create a logical view over either the EDI file, or our application files, that will convert the alpha field to a numeric field in the logical? You can create a logical file that just maps the field to a number field data type. If COL1 was the alpha customer number field in the physical file, the Logical file DDS would just define a new data type for COL1.
COL1 9S 0
SQL Views can also be used. SQL Views are equivalent to non-keyed logical file and actually can be opened as a non-keyed logical file by HLL applications. SQL Views offer superior functions and expression capabilities that logical files. The following SQL View could be created directly over the EDI file. This example assumes that the EDI file is stored as one large character column in an iSeries file & that the customer number is the first nine bytes of the EDI data record. create view v1 (custnum) as (select decimal(substr(c1,1,9),9,0) from edifile)
