Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

Concantenate details on reports

    Concantenate details on reports

    I would like to concantenate descriptions for po line items onto a report into the group footer to give a desc of items ordered for a po.

    example

    PO1111 ABC Company $100.00
    widgets,tape,glue (concant from detail section)
    P01112 BCD Company $200.00
    mirror,paint,cloth

    Total $300.00

    I have tried using a variable in a calculated field.
    cont_desc=cont_desc+trim(po_desc). This evaluates to a logical even though the layout session variable was set as character.

    Any ideas?

    Thanks,
    Anthony

    This is doable with a user defined function involving

    TABLE.EXTERNAL_RECORD_CONTENT_GET()

    If you need help creating it, post back with the table name(s) on which the report is based, the name of the line items description field, the order in which the descriptions should appear, and the name of the po id field.

    Or attach a small sample of the table and support files.
    There can be only one.

      Stan,

      Do I tie this off of a record event in my report? Section even, detail then onrecord? It looks like from the documentation I have to define an array to store the info in and then how do I print this array on the report?

      My table name is: po_items
      Items desc field: description
      Order for fields: (doesn't matter, order they were entered is fine)
      PO ID field is: po_no

      Thanks,
      Anthony

        RE: Concantenate details on reports

        We need to use a function to build the array and then concatenate the array elements into a string. I did one for someone else but Selwyn did it better. Borrowing his function and substituting your parameters.......

        function names as c (po_no as c)
        list = table.external_record_content_get("po_items","description","","po_no = '"+ po_no+"'")
        list = stritran(alltrim(list),crlf(),", ")
        names = list
        end function

        Create the function on the code tab (copy and paste as there are multiple single and double quotes which are hard to read on the board), go to your report, design a calculated field whose expression is

        names(po_no)

        place the calculated field in the po_no group footer and specify "value".

        The function gets all the po_items descriptions for po_no = current_po_no_at_time_group_is_evaluated. Takes the crlf() delimited string and makes it a comma delimited string
        There can be only one.
