Why can I not associate an attribute of a Dimension Dense?

It is more of a theoretical question rather than to a specific need, but I do not understand why it is not possible to associate a dimension of a Dense dimension attribute. The SER60 said what follows, but does not explain why:

"Dimensions with the associations of the attribute cannot be on Dense. Essbase allows associations of the attribute to be set as Sparse dimensions only. »

Everything I've read attribute Dimensions offer more features in all cases compared to a UDA except that the Dimensions of the attribute can be associated with the dense dimensions. Obviously UDAs can be associated with the dense Dimensions, so why not add this to the Dimensions of the attribute and throw UDAs completely?

I considered the possibility that attribute Dimensions require a to-many with their associated dimension (Eg. Several products that are 12 ounces), and all aggregates can be associated with a member (for example. A single product marked in 12 Oz, 14 Oz, etc.), but I can't really think a realistic instance where you WOULD multiple attributes associated with a single member.

Also consider a few other things. UDAs have always existed. Dimensions of the attribute are not arrived on the scene until 6 version (I think). You would not take away the existing functionality of UDA during the presentation of the attributes. Other things to consider. A UDA can be used on several levels of a cube dimension in a one attribute. If I wanted to do something stupid like dynamic calculations ot several levels if a certain UDA is where you can, but could with attributes. Or how about the fact that a member cannot have a member of an attribute, but several udas. Yes woth attributes, you might not have to if plurivalent statement. Say you have products that are color products are sold as some like red and others come in two blue colors. With an attribute to tell me how to have a calculation where the product is both blue and red.

Some examples of the differences. There are many more. I understand your attributes you want to do all things, but sometimes there are reasons for it not. Since there are no blocks in the ASO cubes, the restriction goes away, but of course, you can currently do calculations procedures (yet)

  • Why can I not use hidden or display point only to store the value for insertion?

    Hi, gurus:

    I have a question:

    I implemented a form with the region of report in a page, the update works OK, but the add function has a problem:

    There is a column, offender_ID, which is a foreign key to another table, it must not be null during insertion. However, even I pass the ID of the author of the offence of master page when user click on the button create and he did watch in the form, it must be a text tabled for insert success, why can I not use hidden or display point only to store this value for insert? (If I use hidden or display single element insert will be successful, apex reports I tried to insert a null value for the offender_ID column.)

    Thanks in advance.

    Hello

    There is a column, offender_ID, which is a foreign key to another table, it must not be null during insertion.

(If I use hidden or display single element insert will be successful, apex reports I tried to insert a null value for the offender_ID column.)

    I think that both hidden and display elements have attributes that can cause problems because of different ways these function elements as the only non-display and feature no hidden items. The only items have a "Save Session State' yes/no 'control'? This can be a problem.

    Would you do that? Do these regular items instead and see if you can get those working. Then, we will try to change the fields back to hidden or display only.

    Congratulations. I'm glad you found the solution.

    Why can I not use the SHIFT key to select several thumbnails of Pages?  I need to transfer several pages in the Pages of a document to another document, and I can't select these multiple pages in the thumbnails by pressing the shift or command key.  Help, please!

    By selecting several thumbnails, and copy and paste any thumbnails in another document of v5.6.1 Pages is not supported. You get to select the contents of a real individual page and then copy and paste between documents.

    In Pages ' 09 v4.3, you can select several thumbnails and then copy / paste these in the Gallery of thumbnails of another document. If the Pages ' 09 has been installed prior to any publication pages v5, older Pages move silently in Applications: iWork ' 09 file. You would have to export your content Pages v5.6.1 as document Pages ' 09 for backward compatibility.
