Schedule_ship_date not to sat ,sun (Holiday) in report in oracle

Question

Hi All,
I have the below query in which the column (ool.schedule_ship_date - (DECODE(planning_make_buy_code,2,NVL(ceil(POSTPROCESSING_LEAD_TIME) ,0) + ceil(NVL(FIXED_LEAD_TIME,0)),ceil(NVL(FIXED_LEAD_TIME,0))+ ceil(NVL(VARIABLE_LEAD_TIME,0)))) schedule_postprocesing) gives the details of schedule date but the requirement is the it will not take the holiday(Means sat, sun) in the report.
Could you please help me how to modify this column so that it will not include the sat,sun dates.

Answer 1

1) The query does not run. Please run it yourself before posting a question.
2) You seem to be simply adding variable_lead_time in your calculations. Is your order quantity always 1? If not, you need to multiple the variable lead time by the quantity.
3) When posting query, use the tag to make it readable.
4) Remove unnecessary columns /clauses /comments from the query before posting.  e.g. in your select, leave in only the lead time related columns
5) Does your client use pre-processing lead time?  If they do, you may have to include it as well.
6) Typically, the supplier lead time is given in calendar days for purchased items.  Why would you treat it differently?
And finally the probable answer to your question
Say you have a scheduled_ship_date of 15th Mar and your lead time calculations come out to be 20 days.  As you mentioned, you would like to back up 20 work days from Mar 15.
Here is what you do:
Identify the calendar to use (most likely from mtl_parameters.calendar_code)
Find the sequence number for 15th Mar from bom_calendar_dates for that calendar code.
Substract the 20 from the sequence number.
Identify the date from bom_calendar_dates for that new sequence number.
That is your answer.
