PM44346: CHILD SEGMENT WITH NEGATIVE KEY VALUE NOT RETREIVED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the developer selected a database record using the key of
  the root segment, File manager retrieved both the root segment
  and 2 child segments (one child key with positive value and one
  with a negative value).  When the developer selected a database
  record using both the root segment key value and child segment
  key with a negative value, File Manager did not return any
  segments.  The developer was expecting to see one root segment
  and one child segment.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All FM/IMS users.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: When editing or browsing a database     *
  *                      with a view that has selection criteria *
  *                      that reference numeric fields, FM/IMS   *
  *                      may not display all the segments that   *
  *                      satisfy the selection criteria or may   *
  *                      display segments that do not satisfy    *
  *                      the selection criteria.                 *
  *                      The problem occurs when FM/IMS converts *
  *                      expressions that reference numeric      *
  *                      fields into qualified SSAs.             *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  To refer to a field in a selection criteria, you specify the
  field's reference number prefixed by # or #u.
  When an expression specifies a numeric field's reference number
  prefixed by #, a comparison operator and a numeric literal,
  FM/IMS should interpret the field value as a numeric and perform
  a numeric comparison.
  If none of the fields defined in the DBD match or partially
  match the numeric field specified in the unit expression, FM/IMS
  performs a numeric comparison as it should.
  If, however, there is a field defined in the DBD that matches or
  partially matches the numeric field specified in the unit
  expression, FM/IMS converts the unit expression into a qualified
  SSA and IMS performs the comparison.
  When evaluating expressions in qualified SSAs, IMS performs a
  byte-by-byte binary comparison and not the numeric comparison
  that is required.
  

Problem conclusion

• FM/IMS has been modified to not convert expressions that
  reference numeric fields into qualified SSAs when the expression
  specifies the numeric field's reference number prefixed by #.
