Function Module - Calculate Previous Week

Hi Guys,
I am looking to create a variable on Fiscal Period/Year, that automatically populates the variable with the previous week (current week minus 1), when the user runs the query.
I have heard there is a Function Module available - can anyone help?
Thanks
Scott

Hi,
use the following code:
DATA: l_curr_week LIKE SCAL-WEEK.
DATA: l_prev_week LIKE SCAL-WEEK.
DATA: l_day TYPE DATS.
CALL FUNCTION 'DATE_GET_WEEK'
EXPORTING
    date               = SY-DATUM
IMPORTING
   WEEK               = l_curr_week.
CALL FUNCTION 'WEEK_GET_FIRST_DAY'
EXPORTING
    week               = l_curr_week
IMPORTING
   DATE               = l_day.
SUBTRACT 1 FROM l_day.
CALL FUNCTION 'DATE_GET_WEEK'
EXPORTING
    date               = l_day
IMPORTING
   WEEK               = l_prev_week.
hope this helps...

Function Module - Calculate 5 weeks lookup based on -7 increments from the Key Date

Hi Guys,
I am looking to create a variable on Fiscal Period/Year, that automatically populates the variable with the previous 5 weeks based on -7 increments from the key date , when the user runs the query .
For Example: If key date is 03/11/2014 need to get previous 5 weeks 03/04/2014, 02/25/2014, 02/18/2014, 02/11/2014, 02/04/2014. mm/dd/yyyy.
Is there any Function Module available/ please provide the logic code - can anyone help?
Thanks,
Suresh Narayan

Hi suresh,
Please once try with this approach,
Create a variable with variable represents : multiple input value, Processing type : customer exit ; variable is ready for input.
and write the below code :
if i_step = 1.
data : fdate type d ,
wa1 like line of e_t_range,
n1 type i.
n1 = 1.
if n1 <= 5.
wa1-opt = 'EQ'.
wa1-sign = 'I'.
wa1-low = fdate.
append wa1 to e_t_range.
fdate = fdate - 7.
endif.
endif.
Hope you got it,

Date Function to get Previous week

Is there a date function to get
Let us say today is 23rd of Jun 2009
I want a date function to get previous Thursday 18 Jun 2009
and another function which get 7 days before which is Friday 12 Jun 2009.
FYI: For the current week, I was able to use:
select next_day(case to_char(sysdate,'Day') when 'Thursday' then trunc(sysdate-1) else trunc(sysdate) end, 'Thursday')
from dual;
select next_day(trunc(sysdate-7), 'Friday') from dual;
I want something similar to that.
Thanks

No, not separate functions, but you can tweak next_day to get what you want:
select trunc(sysdate) today,
       next_day(trunc(sysdate)-1, 'THURSDAY')-7 last_thursday,
       next_day(trunc(sysdate)-1, 'FRIDAY')-14 prev_2nd_friday
from   dual;
TODAY     LAST_THUR PREV_2ND_
23-JUN-09 18-JUN-09 12-JUN-09

What is function module get previous date by enteing no of days

FM should take : 7 days
and should return : 4.12.2007
as output.
Thanx,
Naveen

Hi,
Apart from function module, you can write as follows.
data : date1 type datum,
date2 type datum.
date1 = sy-datum.
date2 = date1 - 7 .
write date2.

Function module SD_SCHEDULING: delivery date calculation factory calendar

Hi,
When I create or change a sales order, system calculates the delivery time and date (ETDAT) using transit duration and factory calendar. Currently factory calendar says that transportation leaves every Monday, Wednesday and Friday. Unfortunately, function module SD_SCHEDULING calculates the delivery date using factory calendar dates, i.e. NOT using working dates.
Function module reads the factory calendar from table TVRO (Routes) and field SPFBK (Factory calendar key) in subroutine GET_CUSTOMIZING, and saves factory calendar id in CS_SCHEDDU-TRANSIT_FC. The calculation itself is done later in function module DATE_CONVERT_TO_FACTORYDATE.
For example, if transit duration is 3 working days, function module calculates the delivery date using Monday (first day), Wednesday (second day) and Friday (third day). Thus, the result is Friday, which is wrong. Result should be of course Wednesday (Monday first day, Tuesday second day and Wednesday third day).
I'd like to use working days instead of calendar days. I am planning to recalculate the delivery date in some user exit, but before I start coding, I'd like to hear your opinion: Is it possible to use working days instead of calendar days when calculating delivery date? (I believe it must be, since my case is very normal). If it is, I assume that this can be achieved with IMG, but how and where?
I am using SAP R/3 Enterprise.
Regards,
Jarmo Tuominen

Hi jarmo,
1. DATE_CHECK_WORKINGDAY
 Probably this FM may be useful to u.
2.
CALL FUNCTION 'DATE_CHECK_WORKINGDAY'
 EXPORTING
 date = d
 factory_calendar_id = '01'
 message_type = 'I'
 EXCEPTIONS
 date_after_range = 1
 date_before_range = 2
 date_invalid = 3
 date_no_workingday = 4
 factory_calendar_not_found = 5

WWI issue: function module with symbol doesn't work in conditional output

Hi,
I have created a function module to be used in combination with a symbol that represents the quantity of a composition item in a composition. In some cases a average quantity is not filled and the function module calculates the quantity based on the lower and upper limit of the composition item. This function works perfectly if managed in customising with a symbol or called with a symbol in WWI. When displaying the result of the symbol in a WWI word template it shows the expected value.
However when I use the symbol with a function module (or the customised symbol with function module) in a conditional output expression, the value it represents in the expression is always equal to zero. It seems that a symbol value that is calculated using a functional module is not calculated properly when used in a conditional output expression. Setting a break in the functional module always shows the correct value, but the value as I already told, is not seen by the conditional output expression. Within the expression the value is always equal to zero.
Does anyone know if this is a known issue in WWI? Is there any solution to handle this problem? I hope anyone can help.
Thanks,
Paul

Dear Paul,
only some add on high level ideas:
if you look at:
Example: Layout of an Abridged Material Safety Data Sheet - Basic Data and Tools (EHS-BD) - SAP Library
you find the standard example of SAP for master and slave group:
2 <11BRG003 (M,SAP_EHS_1012_004;*)> ¶
3 <03EHS_L_TEXT(CED
-SDB-01.002)> ¤
<03EHS_L_TEXT(CED-
SDB-02-07)> ¤
<03EHS_L_TEXT(CED-
SDB-02-05)> ¤
4 <11BRG002 (S:POS;*)> ¿
5 <01GESTRIDENT(I:NAM,
6 IUPAC,;*)> <11ERG002>¤
7
8
9
<11BRG002 (S:POS; *)> ¿
<01G1023001R2(C;*)
><11ERG002>¤
<11BRG002 (S:POS;*)> ¿
<01GESTVPRECL>
<01GESTVCOMPL(N:" ZZ9,9")>
<01GESTVCOMPE>
<11ERG002> ¤
10 <11ERG003>¶
The "issue" is that you need to analyse by "line" of POS group; or precisely: it is easy to print lower, upper and average value if it exists.
In conditional output this example is shown in SAP help:
<15BIF001(AND:01G1013005VA GE 1)><01G1013005VA(;*/TL)[D:Value]>
<15CIF001><03EHS_L_TEXT(CUST-100000000000031)[D:Density is less than 1]>
<15EIF001>
I believe you need a "clever" nesting together with your customer symbol
E.g. you need first "test" the contents of the three values and decide about result
The easiest way could be to use a "table" structure as above.
Just use column header "lower"; "average"; "upper" value. Then you need to ask your self in which situation what need to printed.
If you use the table structure and you print just what is there and leave simply lower / upper limit "field" empty if it does not exists (what is bad with this?) you need only this "conditional" output topic done for average value. You could check for: if value > 0.0001 then print the value (as then there is a value); if not use the report symbol in which you calculate something. In my opinion it is worth to try it.
It is known that you can check "numeric values by using conditional output. I belive tis cintional one des work as well with the "composition" values (lwoer, upper, average),
May be this approach might help.
The "stack" examples which are discussed in SAP help and in the links shown are related to "characteristic" values of classes and not for composition ones.
C.B.
PS: If this really works you can clearly extend your solution. E.g. if lower value is empty may be print "0", If upper valus is empty may be print "100" etc. (or prepare a further costumer symbol calculating something).

Need a Function Module for Week Calculation

Dear Experts,
I want a function module which calculate the week number.
Suppose for date 04.05.2010
week is 19...........
i want to fetch through function module.
i have already tried function module like GET_WEEK_INFO_BASED_ON_DATE & DATE_GET_WEEK
throgh both function module output is come out is 18.
but i need 19.
when i pass 02.01.2010
then it giving 53 week of 2009.
plz. help me as soon as possible.
Thanks,

Jan 2 2010 was indeed 53rd week of 2009, so SAP FMs are returning right value. I would strongly recommend to consult your functional consultant before assuming Jan1 2010 as week 1 of 2010.
[quote from wikipedia|http://en.wikipedia.org/wiki/ISO_8601#Week_dates]
'If 1 January is on a Monday, Tuesday, Wednesday or Thursday, it is in week 01. If 1 January is on a Friday, Saturday or Sunday, it is in week 52 or 53 of the previous year (there is no week 00). 28 December is always in the last week of its year.'
