[AccessD] Numbering Different Criteria

We recommend to separate the main code like:

XXNNNN the fisrt part like Alphanumeric Field with 6 positions
X        only 1 position to identificate Engineering Section
NNN     three digits from and integer value converted to String with filled
0 on the left
NN        revision number
NN        Change number

With this in the future you couldn't have any problems making changes on the
main database or making any query you obtain a very adaptable query.

Good luck

  Asunto: [AccessD] Numbering Different Criteria


  I need to set up a way to assign sequential numbers based on different
criteria.

  The first part of the number is a document number, it can be either AB1234
or CD6789, the next part is for the Engineering section (C for Civil,
M-Mechanical, E-Electrical). So the numbering scheme would be:

  AB1234-C001 (tracking number - section, sequential number)
  AB1234-C002
  AB1234-M001
  CD6789-E001
  CD6789-E002
  CD6789-M001

  The numbers also contain revisions and change letters. If I want the next
Civil number for document tracking number AB1234, it would be:

  AB1234-C003, Rev 0, Ch 0 (document number - section, sequential number,
revision, change)
  then AB1234-C003, Rev 0, Ch A
  or AB1234-C003, Rev 1, Ch 0
  AB1234-C003, Rev 1, Ch A

  I thought if I could have the form select the tracking number & the
section, I could use a query to designate what the next sequential number
would be based on the tracking number & the section. Then I couldn't get the
two different criteria to work together.

     ' Find the record that matches the control.
      Me.RecordsetClone.FindFirst "[DocID] = '" & Me![cboDocNum] & " AND
[Section] = " & Me![cboDocNum] & "'"

  Now I got to wondering how I would handle the Revision & Change Letter.
Any ideas how I can put all this together?
