REVERSE DEVELOPMENT MANAGING SYSTEM FOR REQUIREMENT AND SUPPLYING OF MATERIAL REQUIREMENT PLANNING SYSTEM

摘要

PURPOSE:To shorten the processing time of reverse development, by registering the forefront of requirement and the final requirement number on a supplying record in which requirement records are summarized in a lot. CONSTITUTION:A minimum supplying and a maximum supplying numbers registered in a work area are transferred to areas Si1 and Si2. At this time, a blank is transferred if the work area is blank. Next, if the area Si1 is blank, the requirement numbers from a work area DF to a work area DL are outputted, then, a processing is completed. When the work area is not blank, a designated supplying number in the work area is searched, and the forefront and the final requirement number registered in the supplying record having the designated supplying number are transferred to the DF and the DL. Next, a high-order supplying number registered in the record having the requirement number transferred to the DF and DL is transferred to an SF and an SL. The above processing is performed repeatedly until no record having the high-order supplying number exists any more.
