      We have an interface that changes a batch flat file into a file of HL7 messages.  In our Xlate we translate the flat file fields into the appropirate HL7 equivalents.  Part of this is to place the message count into the BTS 1 field.  We then have a post xlate proc that strips the other HL7 segments from before the BTS and FTS segments.  We see a value leave the xlate in the BTS 1 field via a post statement ‘echo’ however when the message gets to the post xlate tcl script it has a value of 0 in BTS 1.  What would be causing this value to change between the xlate and the script.

      Thanks in advance for the assistance.

          Barb…there could be a couple of reasons for this.  Can you attach some code so we can see what you are trying to do?

            I would be curious to try not stripping out the undesired segments so you simplify the number of steps and see if the BTS-1 field is still 0.

            This will help determine if the post xlate proc that strips off undesired segments is causing the BTS-1 field to become 0.

            I would suggest keep reducing the number of steps until you get the BTS-1 segment to be valued as desired.

            Once you accomplish that then progress forward and start adding back one peice at a time the desired extra steps until you have them all working.

            If it turns out you think your segment stripping proc is the problem I can provide you with one that is knonw to work and we have been using for years successfully.

              Unfortunately the code from the time of the original post is gone.  We have made a variety of changes.  What we ended up doing as the value of BTS-1 at every step was 0 is to perform all formating of the BTS and FTS segments in the post route tcl script.  Things are looking good now.

              Thanks, Barb
